Five Azotobacter and seven phosphate-solubilizing fungi were isolated from sunflower rhizosphere identified, screened for their nitrogen fixation and phosphate solubilisting efficiency. Azotobacher cuultures did not inhibity any fungi; on the other hand, all fungal cultures suppressed the growth of Azotobacter, except three Penicillum cultures (H.F-3,4 and5). Azotobacter cultures GA2 and GA3 increased seed germination but the other three did not. All Azotobacter cultures increased radicale/plumule lenght significantly except GA-1 where it reduced the radicle lenght by 13.6 percent over the control. All fungal cultures showed high deleterious effect on seed germination as well as on radicle/plumule growth as compared with the control. The combined growth Azotobacter cultures(GA-1 and GA-3) with Penicillum (HF-4 &5) and Aspergillus (GF-1 and2) species increased the lenght of both radicle and plumule but the culture combinations decreased the lenght of both radicle and plumule over the control.
